After completing a run of King's Fall after the maintenance, I noticed my Zaouli's Bane pattern progress had been set back from 4/5 completed to only 2/5. Another Raid member confirmed his Defiance of Yasmin progress had also been set back by 1 moving his progress from 4/5 to 3/5. I am certain the progress had been setback as I recieved two Deepsight instances of Zaouli's Bane last week, and two the week prior.
